2 Series IHK eneral Features Description The IHK ceiling-mounted induction terminal units are used in air-water systems to provide a high level of comfort in interior environments with high internal thermal loads in cooling operation. The IHK units are recommended for bulkhead and suspended ceiling installation. Ideal for hotel guest rooms and hospitals. The units include the following components:.rimary air plenum, with one round duct connections for priihk mary air inlet and a distribution of small nozzles with alternative settings. Hot or chilled water (two-pipe installation) or hot and chilled water (four-pipe installation) coil. rille, for supply and diffusion of the combined primary and induced air to the room. Return grille, used also as access for unit cleaning. Available in different perforation designs.... As primary air exits the nozzles, this induces air from the room (which we will call secondary), that flows through the coil, cooling and/or heating, as applicable, and is mixed with the primary air inside the unit before it is supplied to the room through the grille. IHK hinged perforated return grille As in all air-water air conditioning systems, choosing an induction terminal unit has the advantage of using water as a vehicle to carry the cooling or heating power to the rooms, which saves on energy and space compared to all-air A/C systems. In addition, the temperature of each room or independent area can be controlled by adding a 2- or 3-way valve to the terminal unit controlled by the respective room control. aterials The outer and inner housings, nozzle plate are of galvanised steel sheet construction and have a standard powder-paint finish of RAL 9010. Other RAL colours are available upon request. lastic nozzles assembled in sheet metal plate. Supply and return grilles are available in aluminium or steel material. The coil is manufactured of copper pipes and aluminium fins. Detailed view of operating principle
Series IHK 3 eneral Features Advantages The IHK ceiling-mounted induction units are terminal units for central air conditioning installations that provide solutions to meet the needs of the following:.ventilation achieved with primary air.cooling, based on the primary air itself and the water circulation coil.heating, based on a water circulation coil.control. ossibility of individual or combined unit control by room or area, using control and regulation valves in the unit to adjust the water volume and room thermostats.air diffusion based on a grille that ensure effective air diffusion. In addition to the functional advantages described, the IHK units have the following main advantages over conventional HVAC systems (fan coils, VRV, all air, etc.):.high energy efficiency and low life-cycle or operating costs; this advantage is mainly due to the absence of a fan in the terminal unit.lowest maintenance costs; the unit contains no filter or condensate pan to replace or clean and only cleaning of the coil surface is needed (recommended every 2 years).low noise level.no draughts in occupied area.extremely hygienic systems, since no filters, condensation tray and drainage tubing are used..space-saving: smaller air ductwork and equipment units.easy to mount.adaptation to the installation conditions. 1- Supply air grille 2- Return air grille 3 - Supply air connection 4 - Water pipe connections (2 pipes)

6 Series IHK IHK-F The IHK-F ceiling-mounted induction terminal unit from Koolair are specifically designed for use in hotels and hospitals, where the area to be cooled has not suspended ceiling and therefore their installation is in the hall annex. The one-way horizontal supply air and the return is made in the same grille. ODEL A B 900 932 900 1200 1232 1200 1500 1532 1500 The cooling and heating powert are 8% lower than the IHK model whose values found in pages from 11 to 14.
Series IHK 7 IHK-V The IHK-V induction terminal unit from Koolair are specifically designed for installation along the perimeter zones. The unit is installed against the facade, it is not required space on the floor, ceiling or corridor. This model is available with condensation tray.

8 Series IHK Installation The IHK units include a series of hanging brackets on the two upper longitudinal sides of the units, as shown in the following photographs. There are two brackets per side. These brackets have a slot hole to hold a Ø6 mm threaded rod, which is first attached to the ceiling slab to hang the unit. The unit can be fixed directly to the ceiling surface or suspended using threaded drop rods. ODEL A B 900 802 932 1200 1102 1232 1500 1402 1532
Series IHK 9 Volume Regulation and Control Components - Air Control Usually, the constant flow system is used most often to distribute primary air to the induction terminal units. To ensure that the installation is correctly balanced, an extremely important aspect for proper operation of the active chilled beam, Koolair RCCK mechanical self-regulators are used because they ensure self-balancing of the installation. CRC- manual volume control dampers can be selected but require manual balancing of the installation. echanical constant air flow self-regulator, KCR model Ductwork pressure dampers (RVV) can be used to ensure the specific inlet pressure in each beam. If a variable air flow system based on occupancy, for example, is designed, then the minimum design flow rate per unit should correspond to a minimum inlet pressure of approximately 40 a to the beam.
